摘要: 基于集中参数法建立了人字齿行星齿轮传动系统平移-扭转耦合非线性动力学模型,模型中考虑了人字齿行星齿轮传动系统多重啮合间相位关系,提出了计入啮合相位的时变啮合刚度,综合考虑了各构件的支撑刚度、误差激励。研究了啮合相位对人字齿行星齿轮均载的影响,结果表明:理想啮合状态下,均布式人字齿行星齿轮系统中,啮合相位系数为0时,系统均载系数为1,同时抑制了系统平移振动;非均布式人字齿行星齿轮系统中,啮合相位系数为0时,系统均载系数为1,同时抑制了部分平移振动。无啮合相位差的人字齿行星齿轮系统均载系数较相位差不为0时小。微调行星齿轮的几何相位,不改变系统传动比及尺寸;调整行星齿轮齿数关系,虽系统的传动比及尺寸略有变化,但系统的均载系数更小,同时抑制系统了平移振动。在单级人字齿行星齿轮试验台上对不同啮合相位的行星齿轮系统进行了均载试验研究,验证了理论分析结果的有效性。

Abstract: Based on the theory of lumped parameters, a translation-torsion coupling nonlinear dynamic model of herringbone planetary gear train was presented. The model considers multiple meshing phase relationship of the herringbone planetary gear transmission system, time varying meshing stiffness is derived. The support stiffness and error excitation of each member are considered synthetically. The effects of meshing phase on load sharing of the herringbone planetary gear is studied, the results show that:in the condition of ideal mesh, when meshing phase coefficient of the uniform type herringbone gear planetary gear system is 0, the system load sharing coefficient is 1, and the system translational vibration was inhibited; When meshing phase coefficient of the non uniform type herringbone gear planetary gear system is 0, the system load sharing coefficient is 1, and the system translational vibration was partly inhibited. The load sharing coefficient of herringbone planetary gear system with 0 meshing phase is smaller than that with different meshing phase. Geometry phase adjustments don't change the transmission ratio and size of the herringbone planetary train. Adjustments of the relations of planetary gear tooth number, although the transmission ratio and the size of the system will change slightly, but the load sharing coefficients are more smaller, and the system translational vibration was inhibited. The load sharing experimental study of planetary gear system with different meshing phase is conducted on single stage test herringbone planetary gear bench, which verifies the theoretical analysis.
